human right to water
The human right to water entitles everyone without discrimination to
sufficient, safe, acceptable, physically accessible affordable water
for personal and domestic use.
Sufficient. The water supply for each person must be sufficient and continuous for personal and domestic uses. According to the WHO, between 50 and 100 litres of water per person per day are needed to ensure that most basic needs are met and few health concerns arise.
Safe. free from micro-organisms, chemical substances and radiological hazards that constitute a threat to a person's health.BIS 10500
Acceptable. acceptable colour, odour and taste for each personal or domestic use.
Physically accessible. Everyone has the right to a water and sanitation service that is physically accessible within, or in the immediate vicinity of the household, educational institution, workplace or health institution. According to WHO, the water source has to be within 1,000 metres of the home and collection time should not exceed 30 minutes.
Affordable. The United Nations Development Programme (UNDP) suggests that water costs should not exceed 3 per cent of household income.
human right to sanitation
The human right to sanitation entitles everyone without discrimination to physical and affordable access to sanitation, in all spheres of life, which is ●safe, ●hygienic, ●secure, ●socially and culturally acceptable, ●which provides for privacy and ●ensures dignity.
Sanitation is defined as a system for the collection, transport, treatment, disposal or reuse of human excreta and associated hygiene.
DID YOU KNOW ?
● In rural Sub-Saharan Africa millions of people share their domestic water sources with animals or rely on unprotected wells that are breeding grounds for pathogens.● The average distance that women in Africa and Asia walk to collect water is 6 kilometres.● Average water use ranges from 200-300 litres a person a day in most countries in Europe to less than 10 litres in countries such as Mozambique. People lacking access to improved water in developing countries consume far less, partly because they have to carry it over long distances and water is heavy. For the 884 million people or so people in the world who live more than 1 kilometre from a water source, water use is often less than 5 litres a day of unsafe water.
DID YOU KNOW ?
● The basic requirement for a lactating women engaged in even moderate physical activity is 7.5 litres a day.● At any one time, close to half of all people in developing countries are suffering from health problems caused by poor water and sanitation. Together, unclean water and poor sanitation are the world's second biggest killer of children. It has been calculated that 443 million school days are lost each year to water-related illness.● In Tajikistan nearly a third of the population takes water from canals and irrigation ditches, with risks of exposure to polluted agricultural run-off.
DID YOU KNOW ?
● A survey of 5 000 schools in Senegal showed that over half had no water supply and almost half had no sanitation facilities. Of those schools with sanitation, only half had separate facilities for boys and girls. The result was that girls chose not to utilise these facilities, either because they did not want to risk being seen to use the toilet, or because they were warned that these facilities were not private or clean enough. Girls also avoided drinking water at school to avoid urination, thereby becoming dehydrated and unable to concentrate● People living in the slums of Jakarta, Manila and Nairobi pay 5 to 10 times more for water than those living in high-income areas in those same cities and more than consumers in London or New York. In Manila, the cost of connecting to the utility represents about three months' income for the poorest 20% of households, rising to six months' in urban Kenya.
